I have to face Drek without the ryno because I have been buying the gold weapons so I figured a way to beat him without the ryno just stay on the grind rail and fire ur devastator until u kill him YAY! 
R.Y.N.O. V Why? Cause its a minigun with epic music and missle upgrade!
My favorite RYNO is clearly the RYNO 2!
100 ammo 
Mashine gun 
Energy rockets
IT LOOKS COOL 
You know what i mean.
I use to use (lol) it the most on planet Grelbin:
I was just like:
-walks around in the ice-
-YETI jumps out of hole-
-YETI attacks him-
-Hits YETI with wrench-
-more YETIS coming-
-tries to survive-
-running away-
-YETIS following-
-says: "AH JUST FORGET IT! EAT THAT, IDIOT"-
-uses RYNO2-
-boom-boom-boom-dead-
-happy-end-
my fav is the RYNO2
it owns the protopet in 3-5secs, without leaving the plataform
The RYNO IV from Tools of Destrution is my favorite because I can beat Tachyon in less than a minute.
Well, with the RYNO2 you can kill the final boss in 15 seconds 
less than that! More like 10! ToD was the odd one out because it is the only one that doesnt shoots missles, it fires laser beams! But still a good killing machine! The RYNO V is the worst RYNO of the lot! It has no locking whatsoever! Consider yourself lucky if it manages to hit the enemy, let alone kill him! (okay that might be a slight exaduration?)
Yeah, youre right. I mostly just stand in front of an enemy and hold down the trigger and BOOM. But im lucky if i hit the enemy if im not standing in front of him. I think the RYNO in ToD shoots rockets, but a kind of energy beam Rocket or something… first when i bought the RYNO i thought it was totally useless, it didnt even had enough ammo to kill one of the four legged Robots with that Fish in a Jar…(forgot their name..)
here be a funny story! When i first got the RYNO IV i thought it was… Either broken or a joke? I was pressing circle and it would only light up red? If i tapped fast enough though it would fire one beam! Incredible right? Yep i was unfamilliar with how the one in the second game worked! (i thought that fired one devastating rocket?) THEN i one day discovered you HOLD circle? How odd? That led me to return to the second game (a while after realising), oh and by the way at the time i didn't play any other game than R&C soo sometimes i would play PS2 alot. (i still kinda do?) When i saw the RYNO II's full power… I was just like "wow!"
The main reason why i like the RYNO V least is because i dont like when bullets dont hit my enemies.
I could call it a Miss-o-phobia 
Thats why i like the RYNO I, the RYNO II and the RYNO IV more. Because you actually hit the enemy (well of course unless there is an enemy in reach 
)
I also dislike the fully upgraded combuster, it shoots three bullets but mostly only one of them hits…
Its wierd, i kinda get a bad feeling when that happens, i just dont like it

Perhaps you get the feeling your wasting ammo? But in reality when you fire once and 3 bullets come out, it only uses up 1 ammo.

Well, Isn't that why the RYNO V had an ammo capability of 3000? Unlike the other RYNO weapons, this one didn't lock on to it's target, therefore it had the most ammo capability in the series possibly because when you fire it, the missiles miss your targets. Maybe it was just supposed to be made that way…

It also spat out the most bullets per second, which would require more ammo.
That too! My friend would give you a full-blown essay on this subject if he had the opportunity to. *Sigh*
I could give a full-blown essay if I wanted to, but in all honesty I'm too lazy.
